What does it mean that the case in the invention patent is returned to the actual examination and entered into the pending quality inspection case?

Waiting for the quality inspection to draw a case means that the examiner's work has basically ended and the conclusion has been drawn. Next, wait for the quality inspection department to conduct random inspection. If the drawings pass or fail, adopt the inspector's conclusion; If the drawings are unqualified, they will be returned to the examiner for further examination. In some cases, inspectors can get authorization and then wait for quality inspection, so the probability of authorization is relatively high.
